To explore a new strategy for further optimization to the C-3 bioisteric heterocyclic ring of fluoroquinolones,twelve novel fluoroquinolone C-3 s-triazole Schiff-base carboxylic acid derivatives(7a-71) were designed and synthesized with both functionalized sulfanylacetic acid and Schiff-base moieties as the modified side-chain for the C-3 bioisosteric s-triazole ring of pefloxacin(1).The structures were characterized by elemental analysis and spectral data,and the in vitro anti-tumor activity of the title compounds against SMMC-7721,L1210 and HL60 cell lines was evaluated.The preliminary pharmacological results demonstrated that the title compounds possessed more significantly anti-proliferative activity than either the parent 1 or the corresponding amine intermediates(6).In particular,the title compound bearing a fluorine atom (7j) and compound bearing a nitro group attached to benzene ring (71) were comparable to the control doxorubicin against SMMC-7721 cells with an IC50 value of micro-molar concentration,respectively.It suggests that s-triazole ring modified with functional side-chain moieties instead of the C-3 carboxylic group is favorable to the improvement of antitumor activity.

Background:C-MET is expressed in a variety of tumor,and its expression may help to predict the prognosis of patients with gastric cancer. Aims:To explore the association of C-MET protein expression with survival in patients with stage Ⅲ gastric cancer. Methods:A total of 178 consecutive initially treated patients with stage Ⅲ gastric cancer from April 2010 to April 2014 at Beijing Pinggu Hospital were enrolled in this study. The expression of C-MET protein was determined by immunohistochemistry. Kaplan-Meier method was used to analyze the survival in patients with high C-MET protein expression and low C-MET protein expression,COX proportional hazards model was used to analyze the influence of various factors on prognosis. Results:C-MET protein was low expressed in 139 patients(78. 1%),and high expressed in 39 patients(21. 9%). Median survival(25. 1 months vs. 45. 0 months),1-year survival rate(69. 2% vs. 91. 4%),2-year survival rate(41. 0% vs. 84. 0%)were significantly decreased in high C-MET protein expression group than in low C-MET protein expression group(P all <0. 05). C-MET protein expression,N staging,and age were the influencing factor for prognosis of gastric cancer(P all <0. 05),however,gender and tumor differentiation were not related with prognosis(P>0. 05). Conclusions:C-MET protein expression rate is 21. 9% in patients with stageⅢgastric cancer,C-MET expression is significantly associated with survival;1-year survival rate is lower in patients with high C-MET protein expression.

Objective To assess the efficacy and safety of 308-nm excimer laser combined with topical tacrolimus 0.03％ cream for the treatment of childhood vitiligo on the face or neck.Methods Sixty-eight children aged ＜ or =14 years with vitiligo on the face or neck were enrolled in this study,and divided into two groups based on lesional sites,i.e.,skin group with lesions on the forehead,cheek,lower mandible,neck or in the periortic region and mucosa group with lesions in the perioral or periorbital region.All the patients received 308-nm excimer laser irradiation once or twice weekly and topical tacrolimus 0.03％ cream twice daily.Twenty sessions of irradiation served as a treatment course.Efficacy was evaluated at the end of the treatment course.The effects of erythema reaction and cumulative irradiation dose on efficacy were assessed.Results After 20 times of laser therapy,an excellent response was achieved in 78.4％ of the patients in the skin group,and 54.8％ in the mucosa group (P ＜ 0.05).During the treatment,the average frequency of erythema reaction lasting 48 hours or longer was significantly lower in the skin group than in the mucosa group (5.84 vs.9.12,P ＜ 0.01).After 10 and 20 times of laser therapy,the cumulative radiation dose was 4215 mJ/cm2 and 10 453 mJ/cm2 in the skin group,respectively,compared to 3364 mJ/cm2 and 7430 mJ/cm2 in the mucosa group,respectively (both P ＜ 0.01).Conclusions The 308-nm excimer laser combined with topical tacrolimus cream is effective and safe for the treatment of childhood vitiligo on the face or neck.Vitiligo on the forehead,cheek,lower mandible,neck and in the periortic region appears to respond better to this therapy with a weaker erythema reaction than that in the perioral or periorbital region.

Objective To evaluate the post-puncture complications in children,and to evaluate the difference in the occurrence rate of headache and backache between patients who had 1 hour of supine recumbency and those who had 4 hours of supine recumbency,to provide evidence for the standardized lumbar puncture (LP) procedure of children.Methods Inpatients who were older than 3 and had diagnostic LP in the course of their treatment between Nov.2012 and Apr.2013 were enrolled.The LP was performed by the same investigator under the standardized institutional guideline for LP and the information of number of LP attempts,duration of LP and cerebrospinal fluid (CSF) drainage volume were recorded.After the procedure,all the children were randomly assigned into 2 groups:the test group had supine recumbency for 1 hour after LP,and the control group had it for 4 hours.For the first 5 days following LP,reports of headache and backache were recorded by another physician who didn't participate in this study.The difference in the occurrence rate of headache and backache between test group and control group was assessed by the chi-square test or Fisher's probabilities in 2 × 2 table.And a Logistic regression analysis was performed to assess the risk factors for the occurrence of the headache and backache.Results The overall frequency of headache was 4.6％ (4/87 cases).The frequency of headache was not significantly different between the test group (2.4％) and control group (6.7％) (P =0.617).And the overall frequency of backache was 19.5 ％ (17/87 cases),and it was not significantly different between the 2 groups (test group:21.4％,control group:17.8 ％,P =0.668).In a Logistic regression analysis,age (P =0.011,OR:6.884,95％ CI:1.398-33.906) and the previous history of lumbar puncture (P =0.018,0R:0.126,95 ％ CI:0.026-0.618) were significant risk factors for the occurrence of backache.The risk of backache in children with more than 2 times of LP was decreased.And the risk was higher in the children older than 6 years than those younger than 6 years.Conclusions Headache and backache were the most frequent post-puncture complications in children.There was no difference between short duration (1 hour) of supine recumbency and long duration (4 hours) in preventing the occurrence of headache and backache after LP.

Objective:To compare the immediate therapeutic effect and safety between esmolol and lanatoside in con-trolling ventricular rate for patients with rapid atrial fibrillation.Methods:A total of 72 patients with rapid atrial fi-brillation (ventricular rate ≥120 beats/min)were randomly and equally divided into esmolol group and lanatoside group.Esmolol group received first dosage of 0.5 mg/kg intravenously for 1 min,then were observed for 5 min,if ventricular rate still >100 beats/min or decreased <20%,the 0.5 mg/kg esmolol was appended,meanwhile main-tained by 0.05mg·kg-1 ·min-1 via micro pump at first,maintenance dose can increase to a maximum 0.3mg· kg-1 ·min-1;lanatoside group received first dosage of 0.4mg or 0.2mg slow intravenous injection,if ventricular rate still >100 beats/min or decreased<20%,the another 0.2mg was appended.The onset time and adverse reac-tions were recorded after administration.Results:Compared with lanatoside group,there was significant reduction in mean onset time [(39.2±8.7)min vs.(5.6±3.1)min]in esmolol group,P<0.01;compared with before adminis-tration,there was significant decrease in ventricular rate in two groups after administration,P<0.05 or<0.01. On 2h af-ter administration,compared with lanatoside group,there was significant increase in decreasing range of ventricular rate (29% vs.39%)in esmolol group,P<0.05. The total effective rate and adverse reaction rate was no significant difference (P>0.05)between two groups.Conclusion:Intravenous using esmolol is efficient and safe,and it can be regarded as pre-ferred therapy to control ventricular rate in patients with rapid atrial fibrillation.

Objective To explore the expression and function of galanin and its receptor in the female mice of anxiety-and depression-like behavior.Methods In situ hybridization was used to detect the expression of galanin,GalR1,GalR2 and GalR3 in the hippocampus of C57BL/6J female mice.A total of thirty female mice was divided into two groups:experiment group (n=15) and control group (n=15).The experiment group was subjected to the chronic unpredictable mild stress (CUMS) for four weeks,and the control group was not subjected to any treatment.Four weeks later,a series of tests were performed on those two groups,including the sucrose preference test,the novel object recognition test,the open field test and suspension tail test.After behavior tests,the hippocampus RNA was extracted from eight mice in each group to test the expression of galanin and its receptor through qPCR.The rest part of mice were used to mark C-Fos immunostaining in the dentate gyms (DG) of hippocampus.Results The result of in situ hybridization showed that galanin,GalR1 and GalR2 distributed in the Hillus of ventral hippocamous,GalR3 had no positive signal.In the sucrose preference test,the experiment group drunk less sucrose when compared with the control group (P＜0.05).In the novel object recognition test,the experiment group contacted shorter time to the novel object when compared with the control group (P＜0.05).In the open field test,the experiment group had shorter in session time when compared with the control group (P＜0.05).In the suspension tail test,the experiment group had longer immobility time when compared with the control group (P＜0.05).The qPCR result showed that the higher expression of galanin and GalR1 in the hippocampus of experiment group (P＜0.05).More C-Fos positive cells in the DG of hippocampus of experiment mice were immunostained (P＜0.05).Conclusions Galanin,GalR1 and GalR2 mainly distribute in the Hillus of the ventral hippocampus.Galanin may be involved in the anxiety-and depression-like behavior of C57BL/6J through GalR1.

Objective This epidemiologic survey aims to investigate the changes in prevalence and risk factors for non-alcoholic fatty liver disease (NAFLD)in the elderly people who are living within Pudong San-lin region.Methods We retrospectively analyzed annual physical check-up data in 2012 and 2014 for elderly people living in this region (aged≥70years).Demographic variables including age,sex,blood pressure,body mass index (BMI)were recorded.Serum fasting glucose level was determined and liver and kidney function were assessed.Abdominal echo-Doppler examination was performed.NAFLD was diagnosed according to Chinese guideline on management of NAFLD (revised version).Results Among 2127 sub-jects with physical check-up in 2012,the occurrence rate of NAFLD was 27.46% (23.02% and 31.02%for men and women,respectively).Type 2 diabetes was detected in 224 subjects and 33.93% of them de-veloped NAFLD (26.73% and 39.84% for males and females,respectively).Among 1771 subjects who received physical check-up in 2014,the occurrence rate of NAFLD increased up to 32.29%,with NAFLD rate being 29.97% and 34.19% for men and women,respectively.In 185 subjects with type 2 diabetes, 49.19% developed NAFLD (47.56% and 50.49% for men and women,respectively).Thus,compared with the findings during physical check-up in 2012,the occurrence rate of NAFLD was significantly in-creased during physical check-up in 2014 for both male and female subjects of overall and diabetic popula-tions (P <0.05 for all comparisons).Further analysis showed that for 185 diabetic patients who had phys-ical check-up in 2014,systolic and diastolic blood pressures,BMI,and serum levels of fasting glucose lev-el,alanine aminotransferase,aspartate aminotransferase,total cholesterol,and triglyceride were significant-ly higher in patients with NAFLD than in those without NAFLD (all P <0.05).Multivariate regression a-nalysis revealed that BMI,total cholesterol and triglyceride levels were independent risk factors for occur-rence of NAFLD in diabetic patients.Conclusions This epidemiologic survey demonstrates a significant increase in the occurrence rate of NAFLD for the elderly people (especially with type 2 diabetes).Hyper-lipidemia,obesity,and hypertension are major risk factors for NAFLD in diabetic patients.

Objective To summarize the clinical features of histiocytic necrotizing lymphadenitis (HNL) and the lesion of central neural system in children.Methods Data of the 4 cases in Beijing Children's Hospital from January 2009 to December 2014 were reviewed and analyzed,as well as other files of 12 patients from PubMed,CNKI,etc.Results All 4 patients mentioned above started from fever and lymphadenopathy,3 cases had headache,2 cases of them experienced altered mental status,and 1 case had cclampsia.The findings of cerebrospinal fluid (CSF) test was similar to viral encephalitis;2 cases had normal magnetic resonance imaging (MRI) result;1 case with MRI test indicated brain white matter diseases with extensive intracerebral hemorrhage,and 1 case had small range of encephalomalacia in left cerebral hemisphere and cerebral dura mater.Through CSF examination,2 cases were positive to Epstein-Barr viral capsid antigen (EBV-VCA)-IgM,while the 2 other cases had no positive trace of EBV-VCA-IgM.Lymph node biopsy was in accordance with HNL typical changes,1 case was positive for Epstein-Barr virus encoded RNA (EBER).Twelve cases in previous literatures were diagnosed as HNL by lymph node biopsy,and their clinical features of central nervous system were headache and altered mental status.There was no change in pathogen.It is also found that the cases in which CSF was performed had shown being negative.CT/MRI image descriptions involved in temporosphenoid lobe,hippocampus,caudate lobe,leptomeninges,etc.Conclusions HNL can be complicated with lesions of the central nervous system,characterized by aseptic meningitis,encephalitis,etc.The prognosis of most cases is good,a few can have neurological sequelae.HNL may relapse,so long-term follow-up is ne-cessary.Epstein-Barr virus in HNL and lesion of central nervous system mechanism still needs further research.
